package libkpmcore4 3.0.0-1 failed to install/upgrade: trying to overwrite '/usr/lib/x86_64-linux-gnu/qt5/plugins/libpmdummybackendplugin.so', which is also in package partitionmanager 1.2.1-0ubuntu1

[C Schilder]

Not so sure what to tell here.... looks to me like a conflicting plugin library needed by two packages of the same type. partitionmanager and kpmcore(kde partition manager core).
When I take a look at url (https://launchpad.net/ubuntu/+source/kpmcore/2.2.1-2), I see stories about unstable packages. Might be the case again?

Status changed to 'Confirmed' because the bug affects multiple users.

Thanks for taking your time to report this issue and help making Ubuntu better.

Could you elaborate a bit on how this bug occured, did it happen during upgrades or when installing new packages? The reason I'm asking is that it looks like the file in question (/usr/lib/x86_64-linux-gnu/qt5/plugins/libpmdummybackendplugin.so) is in both libkpmcore4 [1] and an older version of partitionmanager [2]. But it looks like the file has been removed (moved here?) from newer versions of partitionmanager [3]. So if it happens during upgrade, it might be that libkpmcore4 is added before partitionmanager has been upgraded to the newer version...

In Debian, new packages are uploaded to "unstable" before they move to "testing" and eventually "stable". Development verisons of Ubuntu mainly sync from Debian unstable, so maybe that is what you're seeing.

By the way, this doesn't really affect debian since it never shipped 1.2.1 (only qt4 version of KDE Partition Manager which has different plugin paths).

Good morning Hans Joachim,

Yes this happened right after upgrading with aptitude.
The only other tools I can find are:
- kpackagetool5
  KPackage Manager
- kpackagelauncherqml
  KPackage QML application shell

But I am almost hesitation free to say or maybe to conclude that these two packages are unrelated to the problem.

If there are things to check, test or anything else, with a little bit of instruction to do so, I'd like to contribute more.

Do we still want to keep this bug open? It only affects upgrade from some older Ubuntu versions. New versions are not affected at all.

[vazcometal (vazcometal)]

Hello,

No, please close the bug and forget it.
I´ll install a 17.10 version of ubuntu when got time to do it.

Best Regards
